[Also in Division B5] Corrugating apparatus comprises a pair of endless bands 54, 55, Fig. 3, each carrying obliquely-inclined slats 105, 107, respectively, which interdigitate with the salts of other band along inner runs 61, 67 thereof to obliquely corrugate a sheet 108. The bands 54, 55 are trained about inlet wheels 56, 57 and 62, 63, respectively, and outlet wheels 58, 59 and 64, 65, the wheels being spaced as shown in Fig. 3 so that the bands 54, 55 in passing around the wheels extend diag anally, i.e. at approximately 45, to the longitudinal direction of conveyor movement. The wheels 56, 57, 58, 59, 62, 63, 64, 65 may be mounted for horizontal and/or vertical adjustment, e.g. vertical adjustment of the wheels 56. 58 may be effected by rotation of a shaft 75 by a hand wheel 76 through worm-and-wheel means 74, 78 and simultaneous vertical adjustment of the wheels 57, 59 is effected through chains (86), (87), Fig. 8 (not shown). The band 54 comprises endless chains 93, 94, Figs. 3 and 11, trained about the wheels 56. 58 and 57. 59 respectively. The slats 105 extend between the chains 93, 94 at approximately 45 to the direction of movement thereof and each has its ends interposed between legs of swivel blocks 97, 100 and connected thereto by pins 99, 102, respectively. Pins 98, 101 normal to the pins 99, 102 connect the blocks 97, 100 to brackets 95, 96 on the chains 93, 94, respectively. Similarly, the slats 107 of the band 55 are mounted on endless chains. A second sheet 124 passes between bands 120, 121 having slats 122, 123 and is similarly corrugated but with the corrugations extending in the opposite diagonal direction to those of the sheet 108. Endless flexible belts 129, 130 are situated intermediate the bands 54, 55 and 120, 121 and convey a plane sheet 131 through the apparatus. Inlet guides 49, 51 for the sheets 108, 124 comprise parallel rods 114 extending between walls 112, 113 and feed the sheets between the corrugating bands at an inclined angle.

Abstract: 1407311 Making electrical connections AMP Inc 14 Aug 1973 [11 Sept 1972] 38340/73 Headings B3A and B3Q [Also in Division H2] An electrical connector 8 for terminating a conductor, e.g. tape cable, comprises a substantially planar stamped out sheet metal contact part 12, connecting yoke portion 14 and connecting part 10 which consists of two jaws 16, 18 extending from the yoke 14 having interdigititating teeth 35, 34, resp., which engage and clamp the conductor of a tape cable 2, after forcible plastic deformation of elbow toggle portion 44 of jaw 16 (Fig. 3). The connector is aligned with a conductor in a tape cable 2, which is positioned between jaws 16, 18, and upper jaw is pivoted downwards by an applied force F1, so that weakened part 38<SP>1</SP> is deformed (Fig. 2). The bottom edge of jaw 16 engages stop portion 24, and then a second force F2 is applied to the upper edge of elbow toggle linkage, while force F1 is maintained. Parts 39<SP>1</SP> and 44 are thus plastically deformed, and the teeth 35 are moved leftwardly so that the conductor is clamped very tightly between teeth surfaces 30, 37 and the insulation thereon is extruded or cracked to expose the conductor and enable electrical connection. The connector may be of phosphor bronze or a cartridge brass. Relaxation of the contact is prevented by the overlapping teeth surfaces 30, 37. A plurality of connectors form part of an electrical connector assembly 97, and are mounted on a carrier 46, of nylon, suitably shaped (see Fig. 5, not shown) and received in a housing 98 with a screw clamp 108 for cable 2. Housing 98 mates with a similar housing (Fig. 9), contact 12 engaging the bifurcated female contact of an otherwise identical connector 8. Fig. 7 (not shown) illustrates an apparatus for performing the connecting process, by means of a double punch, a first punch being spring loaded to maintain force F1 while a second punch provides force F2. In another embodiment (Figs. 10, 11, not shown) an intermediate deformable link (132) between the jaws (122, 124) is provided, and an elongate through aperture (138) extends axially of lower jaw (124) in general alignment with the teeth (136). Forces F1 and F2 are in this case applied simultaneously, obviating the need for a dual action spring load punch as above, and when deformed, link (132) inhibits opening of the jaws.

IPC: B21D1/02
Filed: 1967-08-22
Abstract: 1,198,701. Straightening. VOSS ENG. CO. 22 Aug., 1967 [17 May, 1967], No. 38556/67. Heading B3E. A roller leveller has a bottom set of levelling rolls 28 mounted in a bottom frame member 26 and a top set of levelling rolls 24 mounted in a top frame member, first adjusting means 66, 92 supporting a first side portion 34 of the frame member 26, second adjusting means 68, 90 supporting a second side portion 36 and drive means 258 to raise and lower the portion 34 relative to the portion 36 while maintaining the same longitudinal slope of the frame member 26 and its associated levelling rolls. Drive means 264 similarly changes the height of end portion 36 relative to end portion 34 and a third drive means 248 raises or lowers the side portion 32 while maintaining the same transverse slope of the frame member 26. Drive mechanism.-Wedges 66, 92 are driven simultaneously by the motor 258 which drives actuators 144, 210 and the wedges 68, 90 are similarly driven by the motor 262 via actuators 142, 208. The motor 248 drives the wedges 90, 92 simultaneously, but in opposite directions via the actuators 142, 144. Hence operation of either motor 258, 262 singly produces transverse tilt of the rollers, or together gives height adjustment of the rollers and operation of the motor 248 produces longitudinal tilt of the rollers. Wedge construction.-The wedges 90, 92 are provided with inclined surfaces 112 on which slide disc members 86, 88. The disc members may have part-spherical surfaces engaging in the frame 26. The wedges are provided with transverse bores 118 in which are fitted circular nuts 122. These nuts engage the threaded ends 202 of actuator shafts 194, 194a, so that rotation thereof drives the wedges along a guide member 94. The wedges 66, 68 are generally similar except that actuator shafts 132, 128 are secured in bores in the wedges by pins. Actuators.-Each actuator 142, 144 is provided with a shaft 194 having a threaded portion 196 of different pitch to the portion 202 and engaging in the threaded bore 182 of a wormwheel 164 which meshes with a worm gear 192 on a drive-shaft 190, 220. Rotation of the wheel 164 moves the shaft 194 transversely and wedge 92 is taken along with it. A second worm-wheel 162 is provided with keys 172, 174 so that rotation of the wheel 162 rotates the shaft 194 and the wedge is moved along the guide 94.

Title: Still shade temperature measuring instrument
IPC: G01K13/00
Filed: 1976-09-20
Abstract: 1515057 Measuring "still shade temperature" CANADA MINISTER OF NATIONAL DEFENCE 20 Sept 1976 [23 Sept 1975] 38860/76 Heading G1N The invention relates to an apparatus for and method of measuring "still shade temperature", that is a temperature which is relevant to the chilling of a clothed human body and which is compensated for the effects of body heat loss through clothing, of sun, of wind and of air temperature. The apparatus comprises a bead tran-  sistor 1, transistor T 1  in Fig. 3 (not shown), which is painted white to minimize solar heating and which, in use, is exposed to the sun for producing a signal representative of the thermal resistance Ia of the still air layer on the outer surface of clothing, a diode 2 (diode D 2 ) sheathed in a black circular-knit sleeve 3 for generating signal representing sunlight intensity "#" and a circular metal disc 4 beneath the transistor 1 and diode 2 and painted on its upper face with a matt neutral shade. A pair of diodes 6 (diodes D 1 , D 3 ) are mounted beneath the disc 4 and are shielded from sunlight by a foil dish 7, the diodes generating, in use, a signal corresponding to the ambient or air temperature Ta. In the circuit of the apparatus two ganged potentiometers R3 and R2 are provided these being normally set such that a negative signal is produced which is equivalent to 0À18 of non-evaporative rate of body heat loss H. Further an arrangement comprising a further pair of ganged potentiometers R 4 , R 5  is utilized for providing a signal which is representative of the absorptance α of clothing. "Absorptence" is the fraction of the incident solar radiant energy which is absorbed and turned into heat. The arrangement further comprises an amplifier 12 which controls a light emitting diode D4 which in turn, controls the resistance of a pair of photo-resistors R 6 , R 7 . The photo-resistors R 6 , R 7  are each in series with a corresponding one of the ganged potentiometers R 5 , R 4  respectively and the arrangement is such that the sum of the resistances R 5  and R6 and likewise R 4  and R 7  are automatically maintained proportional to resistance R 5  and inversely proportional to the signal representative of the thermal resistance Ia from transistor T 1 . The circuitry is such that an amplifier 10 produces from the five signals an output signal T ss  representative of the still shade temperature, this signal being given by the Formula:- T ss  = Ta-0À18H + HIa + 230 # α Ia The value of T ss  is displayed on a meter 11. In the embodiment shown in Fig. 1h the diode 2 is enclosed by a test tube 8. This test tube and one of the diodes 6 may be removed Fig. 1a (not shown). In the circuit of this modification the bead transistor monitors both the ambient temperature Ta and the effect of wind HIa. The solar radiation signal is provided by the diodes 2 and 6.

Abstract: 868,369. Oscillation generators. AVIATION, MINISTER OF. Feb. 29, 1960 [Dec. 5, 1958], No. 39273/58. Class 40(5). In a high-frequency generator for eddy-current heating, grid controlled gas discharge tubes T1, T2, are connected back-to-back across a series resonant circuit C1, L1, a positive high voltage supply being supplied to the tubes T1, T2, via a high value inductance L3, and a small protective inductance L2 being connected in series with the anode of T1 When a source of recurrent pulses is supplied to the grid of T1 the first pulse triggers T1 and one half cycle of an oscillation of the circuit C1, L1, occurs. The voltage at the anode of T1 goes negative and this negative excursion occurs across the cathode and anode of T2 and is in effect applied across a capacitive potentiometer formed by the cathode-to-grid and grid-to-anode capacitances of the tube T2. In this way a proportionate voltage is applied to the grid of T2 which when it reaches a value sufficient to trigger T2 produces the second half cycle of the oscillation of circuit L1, C1. The cathode of tube T2 and the anode of tube T1 then execute a positive voltage excursion until the still ionised tube T1 strikes again and another negative half cycle is generated. The tubes T1 and T2 continue to conduct alternately and a damped train of oscillations is generated in circuit L1, Cl, and eddy currents are induced in a conducting body placed within the coil L1. After each train of oscillations the capacitor C1 charges through the inductance L3. A resistor R2 increases the rate of decay of the triggering voltage at the grid of T2 to prevent arcing between the grid and cathode. An additional capacitor C2 in series with a current limiting resistor R1 may be connected across the grid-to-anode capacitance to increase the voltage which appears on the grid relative to the cathode of T2.
